令人困惑的编译错误 [英] Confusing compile error
问题描述
我很困惑，我得到的编译器错误信息是引用
到。有人可以采取一个雄鹅，让我知道我做错了什么？该计划
如下。当我编译它时，我得到以下错误

很抱歉，但我不知道你的意思是什么。请更准确。

I''m confused as to what the compiler error message I''m getting is refering
to. Can someone take a gander and let me know what I did wrong? The program
is below. When I compile it I get the following error

Sorry but I have no idea what you''re point is. Please be more precise.
Remove the semicolon.
